A battery is like a bucket in some ways. If the bucket is empty it take more water to fill it than if it is half full. If a new battery is fully charged and you start right up you only took a little electricity out so it will recharge (fill up) quickly. An old battery is like a bucket with some small holes in it. It takes longer to fill up.Kind of a simplified way to look at it but it kind of works that way.

^^^That is an excellent analogy^^^

In this case, the bucket may have a hole in it so large it never fills up so 10 amps is always running into it. Ie. a plate shorted cell to cell or sediment in the bottom of the case shorting across all the cells.
